S32G3 enable pfe2 jumbo frames fail

[GG0712]

Hi NXP team,

We use the s32g399ardb3 as a reference for our custom design board.

And using BSP35 for our BSP version.

We use RGMII for pfe2 and connect to ksz9031 and use PFE-FW_S32G_1.5.0 for pfe fw.

We can not adjust pfe2 mtu size through ifconfig command and libfci_cli failed to enable jumbo_frames feature

Does pfe can adjust mtu size?

Hello, @GG0712 

Thanks for your post.

From the log, the jumbo frame feature seems not supported.

Since you are working with BSP35, the jumbo frame feature is not supported from the Linux PFE driver perspective, I suggest using the newer version BSP if possible.

I can modify the jumbo frames after upgrade BSP version.

This issue was fixed on pfeng 1.3.0 version, and thanks for your support

Highlights:
    1) HIF netdev
    2) Slave STR support
    3) Graceful shutdown of HIF slave
    4) Support for PFE FW 1.6.0
    5) Jumbo frames up to 9k
    6) Use RT_LMEM on G3 by default
    7) Support external TS clock on EMACs
    8) Lossless Tx
    9) Routing rule monitoring API
    10) Various fixes

Thanks
